A Conversation with Distinguished Professor Shigeto Yamawaki Excitement in a Black Box “The brain used to be a black box. You cannot approach the brain directly, like you can simply biopsy a tumor to study cancer.” Distinguished Professor Shigeto Yamawaki has opened up that black box over the course of his 27-year career at Hiroshima University,… Read more

Shaking Up Surgery

Shaking Up Surgery

New vibrations in old tools allow surgeons to feel what they can’t touch A small vibrating device added to surgical tools could improve surgeons’ sensitivity to different shapes and textures inside their patients’ bodies. Engineers from Hiroshima University have designed the small vibrating device to attach to any existing hand-held surgical tool and be used… Read more

Untwist scoliosis by clipping wings of an overactive ladybird

Untwist scoliosis by clipping wings of an overactive ladybird

People with scoliosis, a twisting of the spine that can occur as a birth defect or more commonly starts during the teen years, are now closer to a genetic explanation for their condition. An overactive gene, called ladybird homeobox 1 (LBX1), is the start of a genetic chain reaction that causes the spine to grow… Read more

Genetic cause of neurological disease identified

Genetic cause of neurological disease identified

Using the genetic information of two different families with three generations of disease, researchers have identified a new mutation responsible for a degenerative and ultimately fatal movement disorder. Through induced pluripotent stem cell techniques, researchers also grew neurons from one patient in the laboratory to be used in future experiments. Spinocerebellar ataxia (SCA) is a… Read more

The tortoise and the hare of spinal neural circuits

After an injury, practicing movements at different speeds improves certain nerve functions Changes in one circuit of nerves, but not another, in the spinal cord depend on how quickly muscles must move to complete a task, according to results from the Human Motor Control Laboratory of Professor Kozo Funase, PhD, at Hiroshima University.  The results… Read more

New targets for reducing nerve pain identified

New targets for reducing nerve pain identified

A specific molecule involved in maintaining pain after a nerve injury has been identified and blocked in mice by Hiroshima University researchers.  These results reveal a promising therapeutic strategy for treating neuropathic pain. Mice with an injury to their sciatic nerve showed less pain after multiple injections of a drug that blocks the activity of… Read more
